I'm using Qt5.3 on 64 bit linux installed with the online installer
package qt-opensource-linux-x64-1.6.0-4-online.run.
The output of querying for Bluez5 is attached.
Greetings,
Andreas

Based on your description the following call fails:
QBluetoothLocalDevice device(QBluetoothAddress());
It is supposed to find the local default adapter but it fails. I have a couple
of questions:
What Bluez version do you use?
What version of Qt are you using?
If you use Bluez 4 please send me the output of the following command:
dbus-send --system --dest=org.bluez --print-reply /
org.bluez.Manager.DefaultAdapter
If you have Bluez5 please send me the output of:
dbus-send --system --dest=org.bluez --print-reply /
org.freedesktop.DBus.ObjectManager.GetManagedObjects
Note that the Bluez5 command will produce somewhat longer output.

Subject: [Interest] Bluetooth example (btchat) not working on linux
Hi,
I cannot get this example code working running under linux with Qt 5.3.
http://qt-project.org/doc/qt-5/qtbluetooth-btchat-example.html
Captured debug output when running on the Desktop:
starting
/home/andi/ims/sensor-fusion/bt/build-btchat-Desktop-Debug/btchat...
qt.bluetooth.bluez: Device does not support Bluetooth or
"00:00:00:00:00:00" is not a valid local adapter
Cannot bind chat server to "00:00:00:00:00:00"
If I cross-compile it for android, start it on the android device and
run "rfcomm connect hci0 XX:XX:XX:XX:XX:XX 5" on a terminal on the linux
desktop, I can communicate with the app running on android by
reading/writing to the file descriptor /dev/rfcomm0.
Can someone given me some hint what could be the problem?
With best regards,
Andreas
